MANIFOLDING APPARATUS.

Specicaton of Letters Patent.

Patented June 9, 1914's.

Application filed May 31, 1913, Serial No. 770,955. Renewed April 30, 1914. Serial No. 835,467.

To all whom it may conce/m Be it known that I, ALBERT KRAUTH, a citizen of the United States, residing at Hamilton, in the county of Butler and State of Ohio, have invented certain new and useful Improvements in Manifolding Apparatus, of which thevfollowing is a specification.

My invention relates to manifolding apparatus for delivering invariable constant lengths of paper within a measured stroke or rotation of an operating crank handle.

This invention may be conjointly used with the apparatus shown and described in a pending application, .filed by me July 1, 1912, Serial No. 706,972, and in certain aspects the improvement relates to means for changing the circumferential lengthsof the master feeding roll. In this apparatus the master-feeding roll has its circumferential length equal to the length of paper comprised in a definite length of blank which it is desired to deliver from the machine, or advance a measured length of paper to each complete revolution of the master feed roll. To overcome the accuracy required in constructing a master feed roll of such charactei' to correspond with a measured length of paper, I have provided means within the circumference of the roll movable concentrically with the axis of the roll to slightly vary the circumferential or feeding surface of the roll, so that it can be accurately gaged and correspond to the prescribed length of paper. With the circumferential surface of the master roll changeable, it can be made to accommodate for the most minute changes in the length of the paper, due, for instance, to climatic conditions and changes, causing the paper to expand or shrink. It also increases the capacity of the machine by rendering it adaptable for various sizes of blank lengths and eliminates special machinery and design for each size.

The apparatus herein disclosed also embodies analogous propelling mechanism, as is made the subject-matter of a pending application filed by me February 27, 1913, Serial No. 751,046, in which the propelling mechanism for the feeding rolls comprises a manipulating crank handle capable of being operated at an accelerated motion4 over the masterfeeding roll for a prescribed paper feeding cycle, wherein the handle makes two revolutions or a plural number of revolutions to one complete revolution of the master feed roll before it is checked or arrested. The advantages of such operation are elaborately set forth in said pending application, and, therefore, will not be reiterated herein.

An object therefore of my invention is to provide a pair of coacting paper feeding rolls with their peripheries urged toward each other, and positively rotated in oppos ing directions by gearing, one of said rolls functioning as a master roll having a circumferential surface equal to the length of strip desirable to be fed or delivered within one revolution of said roll, and means for varying said surface so that it can be slightly increased or decreased.

'Another object of my invention is to provide a pair of coacting paper feeding rolls, one thereof comprising a master feed roll with a circumferential surface equal to the length of paper desired to be fed upon one complete revolution of the master roll, with propelling mechanism possessed of an accelerated motion over the master roll, so that a plurality of revolutions are made to one of the master roll before the motion of the propelling mechanism is checked, together with means for positively checking or arresting the feeding operation after the prescribed length of paper advance,r but releasable for a second paper feeding operation.

The features of my invention are more fully set forth in the description of the accompanying drawing, illustratlng a preferred embodiment of the invention, which forms a part of this specificatiomin which Figure 1 is a mutilated side elevation of a manifolding device embodying my invention. 'F.ig. 2 is a central vertical section through the same.. Fig. 3 is a section on line 3, 3, Fig. 2.

As heretofore expressed, certain details of construction, in the disclosure herein, are made the subject-matter of separate applications for Letters Patent, and I, therefore, will only refer to such features in a general way.

While I refer to the machine as a manifolding apparatus, for issuing or delivering invariable constant lengths of'paper, within a measured or limited operation Jr'or each issuance or delivery, in defining the particular use to which my invention is primarily contemplated, but in a broad aspect may be referred to as paper feeding mechanism for successively delivering predetermined lengths of paper.

In the drawings, 1, 2, represent the side frames of the machine mounted upon the base 3. The side frames form a casing and support for the supply webs of paper to be issued or delivered from the machine. The casing, as a unit., may be of two part or sectional form, one section hingedly mount ed upon thesecond or base section so that the `sections may be swung apart for convenient access to the interior thereof. Two webs of paper 5, 6, are illustrated, the ends of which are fed one upon the other over the writingtable 7, and between a pair of coacting feeding rolls. webs of paper may be employed to meet the various requirements with the cores thereof usually journaled upon yielding supports downward pressure thereonfor yieldingly urging the periphery of the upper roll upon the periphery of the lower roll 11. The circumferential contacting surface of this roll, which engages with the upper roll, is of a length approximately equal to the prescribed or measured length of paper desired to be advanced or fed between the rolls upon one revolution of the roll 11. As the revolution of the roll 11 determines the feed of paper desired for each operation, I will designate it a master roll. In machines, as heretofore constructed, employing such master roll, it was necessary to carefully machine to a definite diameter, so that its circumferential surface would be absolutely equal to the length of'paper to be advanced upon each revolution of the master roll, this necessitating special care and construction for each size of autographic blank comprised in plural numbers in a continuous web and did not permit of slight variations as to size Vof blank, without disturbing the accurate interval feed of the individual lengths. To overcome this difficulty and to enlarge the range' of use of a particular diameterof master roll, I have provided means for varying the circumferential length of the master rolLwhich contacts with the upper feeding roll that it may be regulated to meet slight variations in length of diiferentseries of autographic blanks, and also enable the same to be adjusted accurately for a definite size or length of blank. To accom- Y plish this result, I have provided the Lmaster roll 11 with a longitudinal recess 12, into which a member 13 is inserted. The cir- Any number of Y 15 of the master roll 11, to enable the member 13 to be swung toward and from the edge 15 ofthe master roll, so as to increase or decrease its contacting surface with the upper roll 8. The edge 15 may be angular, so as not to interrupt the continuous feeding surface or contact with the upper roll, which, if the adjustment was too grewt, might otherwise disturb the continuity of the feed.

16 represent screws projected through-an oblong slot in each of the arms 14:, 14:, and into the web or arms of the master roll 11 for securin the member 13 in its adjusted position an thereby make it a rigid element of the master roll. The rolls 8, 11, are con-- nected by a gearing so as to positively rotate the'same in opposing directions, the gearing being preferably of a pitched diameter, equal to the diameter of the rolls.

17 represents a wheel fixed to the master roll 11 in mesh with a gear 18, fixed to the upper roll 8, with the gear 17 of the master roll connected with propelling mechanism, which, in the preferred form illustrated, comprises a series of gears of different diameter in connection with a crank handle for rotating the same. In this respect the crank handle is capable of being rotated at an accelerated motion over that of the master roll, the advantages ossessed in such operation having been ful y set forth in the heretofore referred application.

The ropelling gearing comprises' a gear 19 ixe "to the shaft 15 of the master roll 11, in this instance, preferably mounted exterior of the side frame 2 for convenience in utilizing the particular form of arresting or checking mechanism with which the machine is provided. The gear 19 is in mesh with a gear 20 of smaller diameter to provide for the differential rotation between the-crank handle and master roll 11, with the gear 20 in mesh with a gear21, fixed upon the shaft 22, journaled within the side frames 1, 2, having one end squared to receive the socket of the crank handle 23. The crank handle 23 is preferably of two part form, with they handle portion 211 mounted upon a slide member 25 slidably mounted within the crank member 23, and yieldingly urged away ,from the axis .of the crank handle and provided with a lug extension 26, adapted to engage with a lug or projection 27 rigid upon the gear'19, when the two in their rotation comete a parallel diametrical position, which, owing to their reverse direction of rotation, bind against each other and thereby prevent the further rotation or movement of the crank handle, and must be released for further operation. These stop ,elements provide the confining limits of an operating cycle for producing one rotation of the master roll 11 or for advancing or feeding a measured interval fkfrom the essential features of this invention, namely that of varying the circum- 1 ferential length of the master roll.
